What are the orange and green bars just under your name and above the avatar ???

Carl.

It's like a D&D or MMORPG level. You start at level 1 and gain points for forum activity...everything from posting and starting threads to adding photos. Your bottom bar will fill up until you reach level 2, then it will start over again.

The orange bar is your level. Hover your mouse over it and it will tell you level and points.
